塔里木盆地大北气田白垩系巴什基奇克组为典型的裂缝性致密砂岩储层,低孔、低渗基岩与裂缝形成的双孔隙结构造成储层内部气、水关系复杂。针对此类储层,利用传统的地质和测井方法进行产能评价一直以来都是难点。基于高等渗流力学理论,本次研究认为决定流体产能的参数是地层压差和孔隙毛管压力,只有当地层压差克服了储层中各相流体产生的毛管压力的阻碍,才能从孔隙介质中产出。在分析大量的岩心压汞资料的基础上,通过多元回归建立利用孔隙度、渗透率计算平均孔隙喉道半径的模型,基于孔隙介质中各相流体分布形态,转化得到各相毛管压力及等效压差,建立了利用"压差法"进行产能及流体性质判别的模型。选择大北气田3口井5.测试层段,对模型计算结果的准确性进行验证。在裂缝层段及非裂缝层段,评价结果与测试结果基本吻合,达到了设计的要求。

The Maoling gold deposit, one of the large gold deposits in eastern Liaoning Province, NE China, is an ar- senopyrite-disseminated gold deposit with a resource of ap- proximately 25.t Au and an average Au grade of 3.2 g/t. Six arsenopyrites closely related to Au mineralization of the Maoling gold deposit are dated by Re-Os technique and de- fine a Re-Os isochron with an age of 2316±140 Ma, which suggests that the deposit was formed in the Paleoproterozoic era rather than in the Indosinian period as some early re- searchers suggested. High initial 187Os/188Os ratio of 1.32±0.48 indicates a crustal derivation of the ore-forming material of the deposit, which may be derived from rocks of the Gaixian formation of the Liaohe Group. Furthermore, the result also implies that the age of the Gaixian Formation in the Maoling district is older than 2316±140 Ma.

This paper summarizes the Late Palaeozoic. Indosinian and Yanshanian palaeotectonic settings in theperi-Pacific region of East Asia. On that basis, the Himalayan crustal movement in the region is divided intothe early and late tectonic stages and two principal tectonic phases. From the ocean to the continent, 5.giganticHimalayan formation-deformation belts are distinguished; they are the Northwest Pacific trench-island arcbelt. the Northwest Pacific marginal sea basin bell. the East China Sea-northern South China Seacontinental-shelf down-faulted belt. the East Asian epicontinental rift belt. and the East Asian intracontinentalrift belt. The Early and Late Himalayan tectonic evolution is dealt with. Finally the state of the Himalayan re-gional stress field and its evoution in the region are discussed. It is considered that the mechanism of their for-mation is closely related to the continent-ocean and surface-deep earth interaction.

The development of a plateau is an integral part of the evolution of recent large orogens. This is suggested by the presence of wide regions of high topographic relief in many Phanerozoic collisional belts, with the Tibetan, Anatolian, Altiplano and Colorado plateaus forming the most often cited examples. To date, plateaus have not been documented in Proterozoic orogens. However, if large Proterozoic convergent belts developed plateaus, evidence should be preserved in the geologic *** belts expose deeper crustal levels that are not directly accessible in modern analogues. Therefore, if they represent the final product of a plateau style evolution, their study may give direct insight on the nature of the middle to lower crust beneath modern orogenic plateaus. The Grenville Province of the Canadian Shield is a Mesoproterozoic continental collision belt of Himalayan scale that contains various lines of evidence suggesting an early plateau\|type evolution. Here we discuss this evidence and draw comparisons with the prime example of a present day plateau in a continental collision setting, the Tibetan plateau.

The Kunlun Pass Basin, located in the middle of the eastern Kunlun Mountains, received relatively con-tinuous late Cenozoic sediments from the surrounding mountains, archiving great information to understand the deformation and uplift histories of the northern Tibetan Pla-teau. The Kunlun-Yellow River Movement, identified from the tectonomorphologic and sedimentary evolution of the Kunlun Pass Basin by Cui Zhijiu et al. （1997, 1998）, is roughly coincident with many important global and Plateau climatic and environmental events, becoming a crucial time interval to understand tectonic-climatic interactions. How-ever, the ages used to constrict the events remain great un-certainty. Here, we present the results of detailed magneto-stratigraphy of the late Cenozoic sediments in the Kunlun Pass Basin, which show the basin sediments were formed between about 3.6 Ma and 0.5.Ma and the Kunlun-Yellow River Movement occurred at 1.2 to0.78 Ma. The lithology, sedimentary facies and lithofacies associations divide the basin into five stages of tectonosedimentary evolution, indi-cating the northern Tibetan Plateau having experienced five episodes of tectonic uplifts at3.6, 2.69-2.5., 1.77, 1.2, 0.87 and0.78 Ma since the Pliocene.
